Figure 1. Applications Using the TPS3307-18
description
The TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in
automotive DSP and processor-based systems, which require more than one supply voltage.
The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable
SENSE input allows the monitoring of any supply voltage >1.25 V.
The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the
following supply voltage monitoring table.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
